I've been using this a lot recently as well, but I don't think, Miller's
undocumented suggestion can replace this in all cases. One advantage of the
bang~->switch~ approach is - I believe - that it gets rid of many function
calls: You just let the CPU compute a set of, say 64 samples with basically one
function call per object. But if you send 64 bangs instead, I think, the object
get activated 64 time so you have 64 function calls which should be slower.

Is my reasoning correct?
